Abstract (en)
A piezoelectric/electrostrictive device is formed with a connecting plate, a diaphragm, and a substrate mutually joined such that a joining direction of the connecting plate with the substrate and a joining direction of the connecting plate with the diaphragm are mutually intersected to form a cross, and the diaphragm is straddled between the connecting plate and the substrate. A piezoelectric element is arranged on a surface of the diaphragm, and the diaphragm is convexly curved in a direction perpendicular to two directions forming the cross. The piezoelectric/electrostrictive device is an element for converting electrical energy into mechanical energy such as a mechanical displacement or force or vibrations, or for converting the reverse way, and capable of improving operational characteristics thereof. <IMAGE>
